Bio

My overall research interests are focused on both plant development and abiotic stress effects, with a specifically interest in how the plant hormone cytokinin is involved in these processes. My lab uses molecular, genetic, and physiological approaches to study a set of transcription factors known as Cytokinin Response Factors (CRFs), which are regulated by both cytokinin and stress. A major goal of my research is a better understanding of how cytokinin and stress interact through CRFs in both Arabidopsis and tomato to control essential plant processes and development. My teaching interests parallel my research interests and are focused on plant biology, development, and plant hormones.

Research Areas:
Abiotic Interactions, Genetics, Growth Regulation, Signals and Responses
